Your email address was in plain text and I want to share these forums are crawlable by google and other email address HARVESTERS. Upon your request I can delete your post with your email address that is in plain view.

As to the outbound traffic, I won't look at your picture, but today's worms do that as they try to infect other machines. Same story for email infections and of course P2P programs. What I do next is to track down which machines are doing this. If a virus/worm/trojan/spyware is found it is removed. If P2P is found, then we disable that and leave a copy of the company policy on the user's screen.

It's rarely an issue since we block all but authorised ports. Just email, ftp and http.
